FAUCET.

Application led February 13, 1923. Serial No. 818,833.

To all whom z'bmag/ concern.'

Be it known that I, GEORGE R. LONG, residing at Vaterbury, county of New Haven, State of Connecticut, and a citizen of the United States, have invented certain new and useful Improvements in Faucets, of .which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

My invention relates to a push faucet and has for its object to provide a faucet of this type in which the force necessary to open the faucet will be independent of the pressure o'f the liquid to be drawn off.

In push faucets of the ordinary type the pressure of the liquid to be drawn off acts at all times against the valve tending to hold it' against its seat and to thus keep it closed and in order to open the faucet the valve must ,be forced inward away from its seat against the pressure of the liquid.

When the liquid is drawn from a tank the pressure of the liquid will vary according to the depth of liquid in the tank and consequently the force necessary to be used in opening the faucet will vary and when the tank is full or nearly full the force required may be more than is desirable articularly where the faucet is to be openedl'by pressing against it a glass into which the liquid is to be drawn.

By the present invention pressure of the liquid tending to close the valve and to resist its opening is avoided so that the force necessary to unseat the valve and permit the liquid to flow is only such as may be sufficient to overcome the force of the spring by which the valve is closed and the' force required is always the same whatever the pressure of liquidmay be. v

With the objects above indicated and other objects hereinafter explained in view my invention consists in the construction and combination of elements hereinafter de- `scribed and claimed.

Referring to the drawings Fig. 1 is a side view of a push faucet embodying the invention.

Figure 2 is a longitudinal central vertical sectional view.

Figure 3 is a side view of the' faucet equipped with a lever adapted to be operated to open the valve by pressing against it `the edge lof a glass and 1Figure 4 is a detail view of the hollow p u i Irgi the drawings `1 indicates the outer or forward member of the faucet shell or casin and 2 indicates'the rear member the two being secured together by screw threads formed on the forward end 17 of therear member 2 engaging screw-threads formed on the interior of the cylindrical recess 3 ormed in the rear end of the forward mem- In the forward end of the front member 1 of the faucet shell is formed a cylindrical recess 4 the bottom of which is formed by a partition 5 which separates this c lindrical recess from the chamber 6 from w ich leads the discharge spout 7. Thispartition has, in line with the axis of the cylindrical recess 4, an opening 8 for the valve rod 9.

Between the chamber 6 and the cylindrical recess 3 at the rear end of the front member 1 is a partition 104 having through it, in line with the axis of the cylindrical recess 3, an opening 11. On the rear face of this partition surrounding the opening 11 is an annular valve seat 12.

The rear member 2 has a rearward tubular extension 13 adapted to enter the faucet hole of a liquid containing tank having its rear end screwthreaded to receive the usual retaining nut (not shown) on the inside of the tank and having near its forward end a polygonal flange 14 for rotating it, this flange being adapted to serve as an abutment for a disc 15 carryin a washer 16 to .bear

againstthe outer sur ace of the wall of the 'i' open at its forward end and closed at itsy rear end at its rear portion in rear of the screwthreads 21 for engaging the screwthreads 18, of reduced diameter and provided with openings 22 through its walls.

By reason of the reduced diameter of this rear portion of the plug, an. annular passage a 23 is left between it 'and theinner surface of the forward end of the borey of the rear member 2.

The valve rod 9 is provided within the cylindrical recess 3 with a valve 25 and carries on its rear end a solid cylinder 26 ada ted to enter the bore of the hollow plu t is solid cylinder 26 being so arrange that when the valve rod is in its forward position and the valve against its seat 12 this solid cylinder will be opposite to and will serve to close the openings 22 and when the valve rod is pushed rearward to move the valve 25 away from its seat the forward end of this solid cylinder will be to the rear of the o enings 22 and How of liquid through t em from the annular passage 23 will be unobstructed. 4

An annular washer 27 between the rear end of the front member 1 and the flange 14 of the rear member serves to ensure a liquid tight joint between the two members.

The valve 25 is forced outward against its seat to close the faucet by a spring 30 arranged within the cylindrical recess 4 bearing at one end agalnst a washer 31 which rests against the partition 5 and bearing at the other end agalnst a cap 32 secured on the end of the valve rod 9. Pressure on the head of the cap will force the valve 25 away from its seat and will carry the cylinder 26 inward past the openings 22. On releasing the pressure on the head of the cap the s ring 30 forces the cap outward carrying t e valve rod 9 to move with it.

In the form of faucet shown in Figures 1 and 2 the cap 32 is intended to be pressed inward by the thumb of the operator and'in p order to enable the necessary pressure to be applied projections 33 shaped to .form nger holds are provided on the side of the faucet member 1. In the form shown in Figure 3 the faucet member 1 is provided on its upper side with a lug 34 in which is pivoted the upper end of a depending lever 35 the lower end of which is in position to be pressed against by a glass 36 into which liquid is to be drawn. About in line with the valve rod 9 a link 37 is pivotally connected with the lever 35 the forward end of this link adapted to bear against the cap 32.

When a glass is held beneath the lspout 7 and is ressed rearward against the lower end of t e lever 35 to swing it rearward the `almacene link 37 presses the cap inward'against the force of the spring 30 and thus opens the faucet.

The valve 25 being an inwardly openin valve the ressure o the liquid in the tan from whic itis to be drawn tends to -force the valve against its seat and, in the push faucet as ordinarily constructed, the valve h as to be opened against this pressure of liquid, the pressure varying with the height of the liquld in the tank. By use of the cylinder 26 the liquid is shut oii' so that as soon as the valve is closed and the liquid ir the chamber 6 has drained 0E through the discharge spout, there is no pressure of liquid on the valve 25 to resist its opening. The pressure on the cylinder 26 through the openin 22 is radial and does not tend to force t e valve rod outward.

Having thus described my.- invention what I claim is y 1. In a push faucet a valve rod, an inwardly opening main valve carried by the valve rod, a spring acting on the valve rod to hold the valve to its seat, and a second valve carried by said valve rod in rear of the main valve adapted to cut of pressure of liquid from the tank against the main valve said second valve bein so arranged that the pressure of the liqui from the tank acts against it at ri ht angles to the direction of movement of t e valve rod.

2. In a push faucet an outer member provided with a discharge spout and havin a partition provided with an opening, a va ve arrangedto bear against the inner face of the partition to close said opening, a valve rod for said valve, a s ring arranged to act. on the valve rod to hold the valve in closed position, and an inner member adapted to be secured to the outer member, provided with a rearwardly extending tube to enter the faucet hole of a tank and havin forward end a hollow plugclosed at its rear end and having an opening in its walls and a cylindrical piston carried by the valve -rod adapted to o en and positively close the opening in t e walls of the hollow lug without direct resistance by the liquid in the container.

In testimony whereof I hereunto aix my signature.
